A team of geologists at the University of Houston College of Natural Sciences and Mathematics believes they have found the lost plate in northern Canada by using existing mantle tomography images—similar to a CT scan of the earth's interior. The findings, published in Geological Society of America Bulletin, could help geologists better predict volcanic hazards as well as mineral and hydrocarbon deposits.
"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," said Jonny Wu, assistant professor of geology in the Department of Earth and Atmospheric Sciences. "Volcanoes also affect climate change. So, when you are trying to model the earth and understand how climate has changed since time, you really want to know how many volcanoes there have been on earth."
Wu and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like during the early Cenozoic Era. The rigid outermost shell of Earth, or lithosphere, is broken into tectonic plates and geologists have always known there were two plates in the Pacific Ocean at that time called Kula and Farallon. But there has been discussion about a potential third plate, Resurrection, having formed a special type of volcanic belt along Alaska and Washington State.
Using 3-D mapping technology, Fuston applied the slab unfolding technique to the mantle tomography images to pull out the subducted plates before unfolding and stretching them to their original shapes.

It has finally. The doctor was kind enough to explain to me that the strobe light that is used to check the condition of the artificial lens is a shock to the molecules, and they, in turn, send that shock information to the brain. It takes a while for those molecules to recover and send the message to the brain, so it took about five or six minutes before I could see my way out to the truck.
He was also kind enough to agree to do the procedure on me in the morning, rather than the afternoon, when he usually does them. Which was very kind, I thought!
Now, I’m going to take my silly self to bed. My head hurts.
I hope you have a great night and feel much better tomorrow.
Humans rising up from the dead to make zombie hordes was bad enough.
Now we have to deal with resurrected tectonic plates too? A massive landmass zombie?
How are we supposed to shot that in the head?
I’m not afraid. I’ve lived with Democrats.
Who is this “President Elect Biden” I keep hearing about?
Some old guy.
Thank you.
Hey, y’all.
Thank you for your service.
Thanks.
I just wish it had been longer and more productive.
Ah, it was only eleven hundred days.
Since I only want a million days, it’s no big deal.
To all the men and women who served, the sons and daughters of those who served, the mothers and fathers of those who served, the husbands and wives of those who served, all those who are serving now and those who will do so in the future, Thank You for your Service!
I know I’m a day late in these wishes, but several times yesterday, I was reminded it was Veteran’s Day and promptly forgot it again, even though I have a niece who celebrated her birthday yesterday, and even though I flew the flag, I totally spaced it.
But my thanks is intense and powerful, every single day of the year for ALL of you!
Thanks!
‘Face
:o])
Wear your sandals.
That looks like a little chimera! Sweet!
Good morning.
I slept better than I thought I would, and actually woke up before the alarm went off. THAT is a good thing! But of course, the Tired is perched on my shoulders, waiting to pounce.
I was just settling in to read yesterday when the doorbell rang. A salesman. Most government properties are off limits to salesmen and I should have taken the flyer he proffered to give to Chuck. Anyway, I told him I was well taken care of, thanks.
And the phone went wonky again. I may have to buy a new SIM card. Which is OK. I need my phone.
Good tagline.
When my phone has issues, I pitch a fit - with a firm, distinct voice that causes Shannon to turn up and bitch - at the person who insists that electronic things work. It makes me feel better.
I’m tired, too, even though I was lights out at 8:30. We’ll see how today goes. I have a Spanish volunteers meeting tonight, so I probably can’t go to bed before 9:00.
I get very frustrated when my electronics don’t work because for the most part, they are my social life. The isolation of having CFIDS with no phone and no computer was horrendous. The closest pay phone was a block away and I didn’t always have money to make a call. It also meant no one could contact me except by mail or in person, and that meant, most times, not at all.
That was 25 years ago, but I’ve never lost the panic of not having access to help when I need it. So if the phone or the computer is down, the panic is real.
I understand. I need my email!
Electronics person had “a short change” at 11:00 last night. That means he was supposed to do something with his employer’s network when usage was low. He got to bed sometime after 1:00 a.m. He always assumes these things will go smoothly, even though at least 75% of the time, something goes seriously wrong. Whatever.
If he doesn’t stir this morning, I’ll let the youth have a lie-in.
That to, though not quite so much these days, as long as the phone works.
Yes, I know how those things work. When Igor was working at the radar tracking station outside Gila Bend, he had to be at work at 0200 to relieve the guy who was getting off. Sometimes he got called in early and sometimes, he had to stay late. US Gov’t tracking station work is never 9-to-5.
When DP was still in the Air Force, he had a supervisor who would declare an “emergency” and call him in if the guy was bored standing watch by himself. (Sitting in an office, that is ;-). I answered the phone all the time for like six months, because the guy, I suppose, felt stupid leaving a message.
